A two-way ANOVA yields p_interaction = 0.012, p_factorA = 0.004, p_factorB = 0.020 at α = 0.05. Which interpretation is the most appropriate?

Treat the significant interaction as evidence that at least one main effect is a false positive; remove factor A from the model and rerun a one-way ANOVA on B only.

Since all p-values are below 0.05, conclude that there is no interaction but that both main effects are significant and additive.

Ignore the interaction and report that both main effects A and B are significant since their p-values are both below 0.05, because main effects are primary.

Because the interaction is significant (p = 0.012), the main-effect p-values are confounded by the interaction and should not be interpreted in isolation; investigate simple main effects instead.
